Describe the bug

In the default installation of OpenEMR, there is no validation for the email fields especially in the patient's demography section. This is important as many users of OpenEMR would not know of an option to add this validation after their installation. Moreover, as it is an email field many users would assume OpenEMR already performs some validation for emails, similar to the names field.

To Reproduce

Steps to reproduce the behavior:

1. Create a new patient by filling details in the Name (first name and last name), DOB and Sex from the 'Who' section and enter the Contact Email as 'a' in the 'Contact' section. Click on Save and create a new patient.
2. Click on the 'Finder' section in the top navigation bar and select the newly created patient
3. Open the 'Demographics' section
4. Go to the 'Contact' section
5. Check the value for 'Contact Email'
   A user has been created with an invalid email.

Expected behavior

If the 'Save' button is clicked and an invalid email address is present in the 'Contact Email' or 'Trusted Email' fields, then an error message should be displayed indicating the email is incorrect.
